Teledyne Completes CMU VDL Mode 2 Development

LOS ANGELES - September 6, 2001 - Teledyne Controls has completed development of the VHF Data Link (VDL) Mode 2 router capability for the ARINC 758 Communications Management Unit (CMU). Working closely with ARINC, Teledyne has successfully completed pre-AQP testing and will begin formal AQP acceptance testing at ARINC on September 17th.

Integration of the VDL Mode 2 capability into the CMU supports inter-operability with any dual mode (Mode A & Mode 2) ARINC 750 VHF Digital Radio (VDR), allowing 31.5K b.p.s. digital communication over the new ARINC and SITA air/ground networks. Completion of the VDL Mode 2 development is a crucial step towards CNS/ATM and demonstrates Teledyne's commitment to supporting airline driven ATC initiatives such as Controller-pilot Datalink Communications (CPDLC).
